Blue Mountains and Lithgow Air Watch

Blue Mountains and Lithgow Air Watch is a 12-month air quality monitoring project. Beginning in May 2019, Air Watch will provide a better picture of air quality in the region.

Air Watch involves one temporary air quality monitoring station in Katoomba which will measure fine particles (PM10 and PM2.5), sulfur dioxide, carbon monoxide, ozone, oxides of nitrogen, visibility and meteorology. 12 KOALA (Knowing Our Ambient Local Air) air quality sensors are installed in Katoomba, Springwood, Wentworth Falls (Boddington Hill) and Lithgow to measure fine particles (PM10 and PM2.5) and carbon monoxide.

Crucial to this project are the EPA’s partners including a range of Blue Mountains community groups and volunteers, the Office of Environment and Heritage, Blue Mountains City and Lithgow councils, Doctors for the Environment, Western Sydney University and the Nepean Blue Mountains Local Health District. Local businesses, schools and volunteers are hosting and helping to maintain the KOALA sensors throughout the project. 

Where can I access the data? 

Data from the Katoomba air quality monitoring station is available in near real time through the OEH website.

Data from the 12 KOALA Sensors is available in near real-time through the KOALA website

What can I do to help improve local air quality?

We can all play a part in keeping our air clean. Find out what you can do to help reduce particle pollution and your exposure to it. Changing our habits, such as reducing wood smoke emissions and reducing motor vehicle emissions, can help to improve local air quality.
